Complete guide to demolition, junk removal & site cleanup services. Average cost: $1,500–$15,000
Start My Demo Project →Professional demolition and site cleanup — the essential first step for most renovation projects
Demolition and cleanup services range from a single-room gut to full structure removal, and from a junk hauling appointment to complete post-construction site cleanup. Whether you're clearing space for a remodel, removing an old structure, or cleaning up after a renovation, professional demo and cleanup teams work efficiently and safely — handling debris disposal, hazardous material protocols, and site preparation correctly.
In Southern California, older homes (pre-1978) may contain asbestos and lead paint that require licensed abatement contractors before any demolition work. This is non-negotiable — improper handling creates serious health hazards and significant legal liability.
Homes built before 1978 in Southern California very commonly contain asbestos (in floor tiles, roof tiles, insulation, drywall texture) and lead paint. California law requires testing and licensed abatement before demolition in affected areas. Always have a pre-demolition inspection if your home was built before 1980.

If your home was built before 1980, schedule an asbestos and lead paint test ($300–$600) before any demolition. This is required by California law for renovations that disturb materials. Abatement costs vary widely but must be completed before demo begins.
Removing a structure (garage, shed, addition, pool) requires a demolition permit in most California cities. Your contractor handles this, but budget 3–6 weeks for permit approval. Unpermitted structure removal can create complications when selling.
Before demoing a kitchen or bathroom, identify salvageable items — cabinets, appliances, fixtures, and hardware in good condition can be donated to Habitat for Humanity ReStores or sold. This reduces landfill costs and may provide a tax deduction.
Demo should be scheduled so the next trade (framing, plumbing rough-in, etc.) can follow within 1–2 weeks. An open gut with exposed wall cavities in the wrong season can introduce moisture issues. Keep the project moving.
For large demo projects, your contractor will place a dumpster. Verify HOA rules, street parking permits (required in many LA cities), and neighbor notification requirements before scheduling.

Common questions about demo & clean up services
A kitchen gut typically takes 1 day for a 2-person crew. A bathroom takes 4–8 hours. Full interior demo of a 1,500 sq ft home takes 2–4 days. Add 1–3 weeks if asbestos or lead abatement is required before demo can begin.
Yes — demolishing any permitted structure (garage, addition, etc.) requires a demolition permit. Removing unpermitted structures (many sheds, older additions) may not require permits, but check with your local building department. Your contractor will advise.
Junk removal in Southern California typically costs $300–$600 for a partial truckload and $600–$1,500 for a full truckload. Factors include the volume of junk, weight (heavy materials like concrete cost more), and whether items require special disposal (electronics, paint, tires).
Most construction and demolition debris in California goes to a licensed C&D recycling facility where metal, concrete, wood, and drywall are separated and recycled. California diverts 65%+ of C&D debris from landfills. Hazardous materials (asbestos, lead paint) go to licensed hazardous waste facilities.
Basic interior demo (removing drywall, cabinets, flooring) can be done by a general contractor or handyman on projects under $500. Larger demolition projects, any work involving hazardous materials, and structure removal require a licensed contractor (B license minimum in California).
